The metal bushings 28 and the associated bolts 25 are placed as close to the outer ed' es of the wheel as practical.

3. In a wheel, the combination with a rubber annulus having a centrally disposed annular air chamber, there being a medially disposed annular recess in each side of said of two metal disks, each metal disk having an annular bead at its periphery to engage one of the annular recesses in said annulus, a spacer secured to said disks to space said disks from one another with said annular beads in anchoring engagement with said annular recesses, and a felloe iioatingly anchored between said disks and in engagement with said rubber annulus.
